RPC-PET: status and perspectives
M. Couceiro; A. Blanco; Nuno C. Ferreira; R. Ferreira Marques; P. Fonte; L. LopesThe status of the RPC-PET technology for small animals is briefly reviewed and its sensitivity performance for human PET studied through Monte-Carlo simulations. The cost-effectiveness of these detectors and their very good timing characteristics open the possibility to build affordable TOF-PET systems with very large fields of view. Simulations suggest that the sensitivity of such systems for human wholebody s...
Tetra-amelia and lung hypo/aplasia syndrome: New case report and review
Sousa, Sérgio B.; Pina, Raquel; Ramos, Lina; Pereira, Naigel; Krahn, Martin; Borozdin, Wiktor; Kohlhase, Jürgen; Amorim, Marta; Gonnet, KatiaTetra-amelia is a rare malformation that may be associated with other anomalies and is usually inherited in an autosomal recessive pattern. We describe a fetus, born to a nonconsanguineous couple, with tetra-amelia, bilateral cleft lip and palate and bilateral lung agenesis, without other anomalies. Karyotype was normal (46,XX) and premature centromere separation was excluded. No mutation was identified upon mo...
Metabolite Profiling of Human Amniotic Fluid by Hyphenated Nuclear Magnetic Res...
Graça, Gonçalo; Duarte, Iola F.; Goodfellow, Brian J.; Carreira, Isabel M.; Couceiro, Ana Bela; Domingues, Maria do Rosário; Spraul, ManfredThe metabolic profiling of human amniotic fluid (HAF) is of potential interest for the diagnosis of disorders in the mother or the fetus. In order to build a comprehensive metabolite database for HAF, hyphenated NMR has been used, for the first time, for systematic HAF profiling. Experiments were carried out using reverse-phase (RP) and ion-exchange liquid chromatography (LC), in order to detect less and more p...
Ventricular resynchronization through biventricular cardiac pacing for the trea...
Galvão Fº,Silas S.; Barcellos,Cecília M. B.; Vasconcelos,J. Tarcísio M.; Arnez,Jaime G. M.; Couceiro,Kátia N.; Campos,Leudo; Sbaraini,EvandroOBJECTIVE: The biventricular pacing (BVP) approach has good results in the treatment of congestive heart failure (CHF) in patients (pts) with disorders of intraventricular conduction. METHODS: We have applied BVP to 28 pts, with left ventricular pacing using minitoracotomy in 3 pts and the transvenous aproach via coronary sinus in 25 pts. The mean duration of the QRS complexes was 187 ms, in the presence of the...
